Alice, I've been having the same feelings as of late. I think everyones reply posts are some great advice. I'm just starting down this road and I look @ myself in the mirror and think "no way is this going to happen". I see my male features, I think about my family and friendships, my age, my damn hair or lack there of and say "can't do this". I've decided to take it day by day (i know duh!?!). Gotta lose the weight, get into counseling and then we'll see where I'm @ next year (39 y/o) and go from there.
I gotta DO something, I've felt the way I do since childhood.
As a side note, I work in the mental health / sub. abuse field (go figure right?) and I know you know this, but please no more alcohol. It's a depressant in and of itself especially in large quanities. Not a good companion when you're already so deeply depressed.
Hope you are doing better.
